Is there a way to store the WIFI drivers on a USB drive as my WIFI won't work from the live ISO until I installed it from a wired connection

When booting from a live ISO, the WIFI is unavailable available and I’m forced to plug a wired connection into the machine and install online and then the WiFi works fine. The issue is that the machine in question is not a laptop and it can be a pain to have to move it across the building every time I need to reinstall the OS (I mess it up sometimes).

Can I get the WiFi drivers that work, I assume from pacman, and put them on a USB drive so I don’t have to move the machine?

It’s not the end of the world but that
would be such a great help.

Sure, just download the package and put it on the drive.

Then install it with sudo pacman -U /path/to/package


The easiest thing to do is see what is loaded on the live ISO and compare it to the installed system to see what is different and add that to the live iso prior to installation. Can you post inxi -Fxxxza --no-host?

Like already said above, could you

  • show us the inxi output
  • tell which wifi driver package is working for you


How do I find out the WiFi package?

Copy and paste the text here and format it with three backtics before and after the text.

Sorry, I was being stupid. Here you go:

I have installed the broadcom-wl-dkms package. I was thinking that was the WiFi package I needed, am I correct or not?.

What other steps do I need to take? Do I need to explicitly turn the WiFi on on the command line for example?

"dkms" is a module to build into the kernel, it rebuild itself on every kernel upgrade, or if you install a different kernel, for a live iso you may want to download and keep “broadcom-wl” pkg, search in /var/cache/pacman/pkg for the packages stored on your system, i don’t know for a fact if installing broadcom-wl after booting from the live usb will activate your wifi card, but you can expriment to see if that help’s you.
